Which outcome occurs in a pneumatic actuator when supply pressure exceeds the actuator's design limits?

💡 Explanation

When pressure exceeds design limits, stress on the actuator's diaphragm/seals exceeds material strength, causing catastrophic rupture because of overpressure, leading to compromised sealing. Therefore diaphragm or seal rupture results, rather than valve erosion, optimized performance or flow reduction which require specific valve dynamics or fluid behavior.
